Domestic hot water
using heat pump technology

Extra slim unvented hot water cylinder

When upgrading
a hot water system to use heat pump technology you may
encounter issues with cupboard space. This useful addition
to the Stainless Lite unvented cylinder range now offers a
solution.

Building on
a proven track record this new unvented cylinder has been
developed to utilise the lower temperatures generated
through Heat Pump technology to provide your property with
mains pressure domestic hot water from a cylinder with only
475mm diameter.

The Stainless Lite HP
cylinder is available in two sizes - 180 litres and
210 litres.

Despite its reduced diameter the
Stainless Lite HP cylinder still boasts a 3m2 high performance
corrugated coil which has been developed to achieve maximum heat
transfer. The heat exchanger is a totally new design. It consists of
a multi-pass corrugated stainless steel tube in parallel to reduce
pressure loss whilst maximising the heat transfer and ensuring the
high flow rates essential to work with heat pumps.

Due to the fact that many heat
pumps will not raise the stored water temperature to 60 degrees C,
which is necessary to prevent the growth of Legionella, the
Stainless Lite HP model is supplied with an immersion heater tapping
and thermostat pocket.

It is recommended that a thermostat
is fitted which brings the immersion heater 'on' at a temperature
just below the heat pump maximum and switches 'off' at 60 or 65
degrees C. In this way the use of 'direct' electricity is minimised
and most of the water heating is achieved through the heat pump.
